The term Stannerz is used to describe the process of ejaculating in an unusually premature time of under one minute during the act of sexual intercourse.

The term Stannerz can also be used as a time scale for other day to day activities, where one Stannerz is equal to, or less than one minute. A five minute task could be described as taking '5 Stannerz'

Whilst a relatively new term, the term Stannerz is spreading fast.

I hear when they had sex he came in less than a minute?!
Yeah, he did her in a Stannerz!
